Description
This application is a 371 of Application PCT/EP96/00779, filed on 26 Feb. 1996, which in turn claims foreign priority to German Application 195 08 266.4 filed 8 Mar. 1995.
The invention relates to a cover for a machine bed of a machine tool with covering boxes which can be pushed telescopically one inside another.
A covering box for covers which can be telescopically lengthened and shortened for slideways on machine tools is known from DE 40 26 609 C1. The covering box has a top wall and two side walls arranged at right-angles to the top wall, which are directly or indirectly connected to an end wall of the box. The covering box further has catches arranged on the end wall, above the side walls, projecting outwards, for the next largest covering box which has a corresponding counter catch. Each side wall has a longitudinal notch or a longitudinal slit on its edge adjacent the end wall, through which the front end of the catch, which is connected in a removable manner to the end wall in the form of a bar, protrudes. The covering box is made from a one-piece sheet metal blank. The longitudinal notches or longitudinal slits are necessary for attaching the catch, in the form of a bar, to the box.
The manufacturing cost for a covering box of this type with a bar is relatively high. In order to ensure that the end wall of the box, on which the catch is fixed, is not bent by the forces occurring when the boxes are displaced, it is known from DE 40 26 609 to weld the end wall to the side walls. The welding procedure must be carried out very carefully as distortion of the covering box can result due to the heat created during welding. Such distortion of the covering box cannot be completely ruled out, so subsequent straightening of the covering box is necessary.
Proceeding from this state of the art, the object of the invention is to simplify the manufacturing of a covering box. This object is solved according to the invention by a covering box for a machine bed of a machine tool with covering boxes which can be pushed one inside another, wherein each covering box comprises a first side wall and a second side wall and a top wall connected to the side walls, and projecting outwards from a side wall at least one catch for the next largest covering box provided with a corresponding counter catch, wherein the catch is configured on a profiled catch section arranged on a side wall wherein the corresponding counter catch is arranged on a side wall of the next largest covering box.
The cover according to the invention for a machine bed of a machine tool with covering boxes which can be pushed telescopically one inside another is distinguished in that the catch is configured on a profiled catch section arranged on one side wall of the covering box. The manufacturing of a covering box, and thereby the cover, is simplified by this configuration of the covering box. The profiled catch section is preferably joined to a side wall of the covering box. The joining of the catch profile to the side wall can be done by screwing. Bores are configured in the side wall for this purpose, through which a screw can extend. According to an advantageous further development, it is proposed to provide the profiled catch section of the surface adjacent to the side wall with a T-shaped groove extending in the longitudinal direction of the profiled catch section, open on at least one end face. In the T-shaped groove, the head and the neck of a screw can be accommodated. When the profile section is mounted, the head lies on the covering box on the shoulders of the T-shaped groove. It is also possible to fit a nut into the T-shaped groove instead of the head. The advantage of the T-shaped groove can be seen in that regardless of the position of the bores in the side wall, a connection can be established with the profiled catch section. The forces affecting the catch during displacement of the covering boxes are transferred to the side wall by the screwing of the profiled catch section to the side wall. The conduction of the forces into the side wall has the advantage that no distortion, or very little distortion of the covering box occurs.
Advantageously, the catch is provided with a shock-absorbing element which is arranged on the surface of the catch. The impact between the catch and the counter catch of two boxes occurring during displacement is dampened by the shock absorbing element. Furthermore, the noise occurring during the impact is reduced. This is particularly important as such covers act as resonating bodies.
It is proposed to provide the profiled catch section with a groove for receiving the shock-absorbing element. The groove is preferably configured in the surface of the catch. The configuration of the groove has the advantage that a simple connection of the shock-absorbing element to the profiled catch section is produced. Furthermore, replacement of the shock-absorbing element is simple. A shock-absorbing element made from felt is preferred. Other substances are possible for the shock-absorbing elements. However, care should be taken that the shock-absorbing elements are not so crushed by the impacts occurring that they lose their shock-absorbing effect.
To further simplify the manufacturing of a covering box it is proposed to connect the rear wall of the covering box to the profiled catch section. The rear wall can be configured as a separate piece. The connection of the rear wall to the profiled catch section can be done by screwing or the like. It is proposed in this respect to the profiled catch section in the surface adjacent to the rear wall, with a T-shaped groove, open at at least one end face, extending in the longitudinal direction of the profiled catch section.
When the covering boxes of the cover are pushed one inside another, the profile section of one box comes into contact with the profile section or the rear wall of the next-largest box. To avoid the impact and the noise associated with it when the covering boxes are pushed together, it is proposed to arrange at least one stop on the profiled catch section, wherein the stop can be brought into contact with a profiled catch section or a rear wall of the next-largest covering box. The stop can be made from felt, like the shock-absorbing element. The stop per se dampens the impact between two covering boxes which have been pushed one inside another. Furthermore, the noise occurring when two boxes are pushed together is reduced by the stop. The stop can be a stop profile which engages in a stop groove configured in the profiled catch section. The stop groove can be T-shaped or a swallow-tail shape.
The profiled catch section can be prepared to the extent that it is already provided with a shock-absorbing element and a stop. If the covering box is to include a rear wall, these individual parts can be prepared together with the profiled catch section as an integral structure, and then joined to the covering box. In this way the assembly time for a covering box is reduced. The counter-catch is preferably a strip arranged on a side wall. The strip is preferably made from brass.
Further features and advantages of the covering according to the invention will be explained with reference to the embodiments shown in the drawings.

It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, as the invention may admit to other equally effective embodiments.
FIG. 1 is a schematic view of a cover 1 in perspective. The cover 1 includes covering boxes 2, 3, 4 which can be pushed telescopically one inside another. Each covering box 2, 3, 4 has a first and a second side wall 5, 6. A top wall 7, configured in the manner of a pitched roof, is connected to the side walls 5, 6. The side walls 5, 6 and the top wall 7 are made from a sheet-metal blank.
A profiled catch section 32 is arranged on the side wall 5. The profiled catch section 32 is provided with an outward projecting catch 30 for the next largest box 4 provided with a counter catch 31. A profiled catch section 32 is arranged on each side wall 5, 6 of a covering box 2, 3 and 4. As can been seen in FIG. 1, the profiled catch section 32 is connected to a rear wall 38.
A shock-absorbing element 34 is arranged on the catch surface 33 of the catch 30. The shock-absorbing element 34 is inserted into a groove 35 configured in the profiled catch section 32. As can be seen in FIGS. 1 and 2, the counter catch 31 lies on the shock-absorbing element when the covering boxes 2, 3, 4 are pulled apart from one another. The counter catch 31 is connected to the side wall 5 of the next-largest covering box by means of a screw 43. The counter catch 31 can also be connected by means of a rivet instead of a screw 43. The counter catch 31 is configured in the form of a strip.
Each profile section 32 is connected to the side wall 5 by means of screws 44. The screw is screwed into a nut 45, which is arranged in a T-shaped groove 40. The T-shaped groove 40 is configured in surface of the profiled catch section 32 lying on the side wall 5.
If the covering boxes are pushed one inside another, a stop 41 lies on the rear wall 38 of the next-largest covering box. The stop 41 is arranged in a stop groove 42. The stop groove 42 extends in the longitudinal direction of the profiled catch section 32.
A second embodiment of a covering box is shown in FIG. 3. The profiled catch section 32 arranged on the side wall differs from the profiled catch section shown in FIG. 2 in that it is not provided a groove for a shock-absorbing element 34.
